Vacuum cleaner dust bag paper is good or non-woven fabric is good?

Vacuum cleaner dust bag paper is good or non-woven fabric is good? The filter grade is good for paper bags, but the use cost is high, and the paper bags can be washed and used repeatedly. Foreign countries basically use paper bags, and domestic use of cloth bags. Because there are not many customers who use vacuum cleaners in China, paper bags are not very easy to buy and the price is high. I suggest you still use a cloth bag. In the past, the filter bag of pure paper has not been abandoned for a long time. Now the so-called paper filter bag material is actually a kind of non-woven fabric. The small packaging bags we usually see like Lipton tea are actually made of non-woven fabrics. The non-woven filter bags used in general industry are mostly made of acupuncture or blown non-woven fabrics. Needle-punched non-woven fabrics are suitable for coarse filtration and are mostly used in places where large particle dust is removed, such as power plants. Blown non-woven filter bags are mostly used in precision environments such as medical and electronic industries. The filter bag of the vacuum cleaner should take into account his working environment. Generally, the household vacuum cleaner can use the ordinary needle-punched non-woven filter bag.
